The DBH 9974 radial shaft seal is a lip seal designed for rotating shafts 80 mm in diameter, with a 127 mm housing and 17 mm height. Its job is to retain lubricant inside the assembly and block dust, water or particles from entering, protecting bearings and bushings in equipment with continuous rotary motion. It is a wear part that should be replaced when an oil leak or shaft play appears.

This DBH 9974 seal has an A 111 design and is identified by its dimensions: shaft diameter 80 mm, housing diameter 127 mm and height 17.00 mm. The sealing lip runs against the shaft and the metal case is press-fitted into the housing. It is a standard component within the radial shaft seal category, intended for shafts that rotate with permanent lubrication and require a barrier against external contaminants.

It is used in gearboxes, pumps, electric motors, transmission equipment and process machinery where shafts pass through a lubricated housing. It also appears in applications exposed to dust or splashes, where the seal keeps lubricant from escaping and the environment from entering the bearing. It is common in corrective maintenance of equipment that runs continuously.

To mount it, check that the shaft has no burrs or wear and that the housing is clean and free of deformation. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, without striking the lip. If the shaft shows a marked wear groove, consider a nearby size or a seal with the lip in a different position. Selection depends on the type of lubricant, the speed and the working temperature.
